Acquired Oral Findings

Acquired oral findings include:

  • Benign Migratory Glosstis
  • Morsicatio Buccarum
  • Pyogenic Granuloma
  • Ulcers
  • Angular Cheilitis (Perleche)
  • Leukoplakia ("White Patch" in the Oral Cavity
  • Oral Hairy Leukoplakia
  • Parotitis

Benign Migratory Glossitis ("Geographic Tongue")
AKA “Geographic Tongueâ€�, Benign migratory glossitis includes loss of filiform papillae on certain areas of the tongue, making it appear smooth, red, and shiny. Usually noted on the dorsum of the tongue, etiology is unknown and self-limiting. Treatment is unnecessary because it does not pose a problem. However, it may be irritated by acidic foods. 

Morsicatio Buccarum
Chronic, often subconscious, cheek biting results in mucosal shredding, erythema, ulcers or leukoplakia in the areas of biting. AKA “Frictional Hyperkeratosis.â€� Usually symmetric along the buccal mucosa. Biting may also involve the labial and lingual mucosal surfaces. 

Leukoplakia: A condition commonly considered precancerous in which thickened white patches of epithelium occur on the mucous membranes especially of the mouth.

Diagnosis can be made on clinical findings. If cheek biting is a manifestation of anxiety, treatment for underlying trigger may be warranted. No need for treatment if asymptomatic.

Linea Alba
In contrast to Morsicatio Buccarum, linea alba is a single white line across the buccal mucosa. Results from irritation of the teeth against the buccal mucosa along the plane of occlusion. No need for treatment if asymptomatic.

Pyogenic Granuloma
Pyogenic granuloma refers to red, painless masses usually located on the gingiva. Characterized by bleeding with minor trauma and caused by vascular overgrowth in response to a local irritant or trauma. Improving flossing and brushing can result in spontaneous regression.

Can be triggered by hormones, such as in pregnancy and puberty. Pyogenic granuloma may require surgical excision and can recur.

 
 
Geographic tongue is a non-pathologic variant of normal.
 
The buccal mucosa is the most common site of chronic biting.
 
Bleeding in response to minor trauma is characteristic of a pyogenic granuloma.
